This clever little tool should be on the belt of every MacGyver type person. If you are ever put into handcuffs this tiny TIHK Handcuff Key ($13) might just come in handy, as it hides snugly on your belt loop. This concealed handcuff key will open any Peerless cuffs which is to say, almost all handcuffs in use today.
I thought it was going to show a video of a person breaking their thumb to slip out of handcuffs (one of them anyway).
